Calculate glass panel weight for rectangular, circular or measured areas, with cutouts, layers, panel count and optional interlayer or hardware mass.
Glass mass = net area × total glass thickness × density × panel count; add separately entered interlayer / hardware mass
Architectural glass panels weigh the following based on nominal thickness:

A 1/2 inch (12 mm) glass panel weighs approximately 6.25 to 6.50 pounds per square foot (about 30.5 kg/m²). A standard 3 ft × 7 ft frameless shower door in 1/2" glass weighs approximately 131 pounds.
Standard architectural soda-lime glass has a specific gravity of 2.50 to 2.52 and a density of 2,500 kg/m³ (approximately 156 pounds per cubic foot).
No. The tempering thermal process rearranges internal stresses to increase impact strength by 4–5×, but it does not alter the glass density or mass.
